Lorises and Pottos: Lorisidae - Behavior And Reproduction

Lorisids (species in the family Lorisidae) are usually solitary animals, each having a specific range for its food searches. However, the home range (place where an animal feeds and lives) of males may overlap that of females. During the day, lorisids may sleep on a tree branch, in a hollow tree trunk, or in the fork of a tree. They typically sleep while curled up, with head and arms tucked between their thighs. While they see well in daylight and dark, they search for food at night. The animals move very slowly and carefully. Sometimes they don't even disturb tree leaves as they pass through. This careful behavior helps them to avoid predators, animals that hunt them for food. While moving through tree branches, they tend to drag their bottoms to mark their trail with urine. If a lorisid hears even the slightest sound that might mean a predator is nearby, it just stops and hangs on to a branch. With strong arms and legs, it can stay that way for hours, until it feels it can safely move again.


When Asian lorisids want to communicate with each other, they make specific noises, or vocalizations. Sounds vary by species, and include panting, hissing, growling, soft and loud whistles, rapid clicking, and chirping. The clicking sound made by infants when separated from their mother is a series of short, sharp, rapid clicks called a "zic" call.

Lorisids may have more than one mate. Pregnancy is from about four to six months, depending on the species. Lorisids usually have just one baby at a time. Babies weigh from 1 to 2 ounces (28.4 to 56.7 grams). After a baby is born, it hangs on to the front fur of its mother's body for a few weeks. Sometimes, as she searches for food at night, the mother may place her infant on a small branch. The infant holds onto the branch until the mother returns. At night, while the mother sleeps, the baby holds onto her belly. As the infant grows, it begins to travel on its mother's back. Then it follows her. As the mother looks for food, she also is teaching her young how to look for, and recognize, suitable food. Young lorisids stay with their mother until they are about a year old, then go off on their own.
